2007–2015: 6-speed automatic (6F50/6F55) front-wheel drive and AWD; 3.5L or 3.7L V6 2016–2018: 6-speed automatic (6F50) or 8-speed SelectShift (6R80 based); 2.7L EcoBoost V6 or 3.7L Replaced by Nautilus in 2019
MKX 6F50/6F55 diagnosis uses Ford IDS or equivalent scan tool. Shudder testing under highway load determines torque converter health. Fluid condition inspection — Mercon LV is specified and incompatible substitutes cause shudder. Solenoid pack replacement covers most P0750-series codes. Torque converter replacement resolves persistent shudder. Valve body work covers cold-start engagement complaints. The 6F55 in EcoBoost applications requires careful pressure testing — higher torque loads reveal clutch pack wear not apparent during light testing.
Ford Mercon LV ATF (required — not Mercon V or Dexron VI); approximately 9 quarts for 6F50/6F55
Fluid service: same day; solenoid pack: 1–2 days; torque converter: 2–3 days; full rebuild: 4–6 days

The 6F50/6F55 is generally reliable with proper Mercon LV fluid maintenance. The main failure modes — solenoid wear and torque converter shudder — are both manageable with timely service.
Ford Mercon LV — not Mercon V or Dexron VI. These fluids are incompatible and cause shudder and accelerated wear. Mercon LV is what we use on every MKX service.
Full rebuild: $2,600–3,900. Solenoid-only repair: $700–1,200. Torque converter replacement: $850–1,450. We quote exactly after inspection.
Yes — the MKX and Ford Edge are platform-sharing siblings. Both use the 6F50 or 6F55 depending on engine, with identical service procedures and shared parts availability.
Torque converter clutch shudder at 40–55 mph is the most common complaint. It's caused by the lock-up clutch slipping under light load. Fresh Mercon LV with a friction modifier helps in mild cases; torque converter replacement is the definitive fix.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
